Classification and application scope of welded pipes

Welded pipe, also known as welded steel pipe, is a steel pipe made by welding steel plates or strips after being rolled and formed. The production process of welded steel pipes is simple, with high production efficiency and a variety of specifications, but the strength is generally lower than that of seamless steel pipes. Since the 1930s, with the rapid development of high-quality strip steel continuous rolling production and the advancement of welding and inspection technology, the quality of welds has been continuously improved, and the variety and specifications of welded steel pipes have been increasing, replacing seamless steel pipes in more and more fields. Welded steel pipes are divided into straight seam welded pipes and spiral welded pipes according to the form of welds.

1、 Classification of welded pipes

Classification method for welded pipes based on their usage: They are further divided into general welded pipes, galvanized welded pipes, oxygen blown welded pipes, wire sleeves, metric welded pipes, roller pipes, deep well pump pipes, automotive pipes, transformer pipes, welded thin-walled pipes, welded special shaped pipes, and spiral welded pipes according to their usage.

2、 Application scope of welded pipes

Welded pipe products are widely used in light structural steel doors and windows, furniture, various agricultural machinery, scaffolding, wire conduits, high-rise shelves, containers, etc. for boilers, automobiles, ships, and buildings. All can meet customer requirements, and special specifications of welded pipes can be processed according to user requirements.
